The target was to achieve at least one order of magnitude decrease in the overall testing time spent on a single LED package. The main goal of the improved throughput of laboratory testing of LEDs facilitate that Delph4LED-style LED modelling becomes an industrial reality. The second overall objective is to assure, that isothermal IVL characterization of the LED packages being aged becomes a feasible option, thus making it possible to create the elapsed lifetime dependent multi-domain circuit simulation model of LEDs.

AB - In their typical application domains, power electronics components (power MOSFETs, IGBTs) as well as high power LEDs are subjects to cyclic operation. The subsequent on-off cycles result in cyclic changes of the junction temperature, resulting in thermo-mechanical stresses at critical thermal interfaces such as the die-Attach layer. Ultimately, in long-Term, these stresses lead to the degradation of such interfaces, causing a continuous increase of the corresponding partial thermal resistances of the overall heat-flow path of such packaged devices. Further thermal interfaces on system level may also be subject of degradation as a result of ageing during the product lifespan.Over the last two decades, structure function analysis has proven to be a powerful tool in laboratory testing to detect the resulting failures such as die attach voiding or delamination. Combining power-cycling tests with thermal transient measurements resulted in commercial test equipment widely used nowadays in reliability testing of power electronics components, but as of today, no embedded, in-situ solution was published that is aimed at health-monitoring and prognostics purposes of such components during field operation. The aim of this paper is to present a method that could automatically generate time series of element values of a Cauer-Type compact thermal model of the heat-flow path power electronics components and power LEDs during their operation. The series of partial thermal resistance values obtained this way allows a quasi-real-Time analysis of the mission profile dependent degradation of the heat-flow path, allowing prognostics purposes, such as estimation of the remaining useful lifetime (RUL) from the perspective of the thermal properties. © 2023 IEEE.

Synthetic metalloporphyrins show structural similarity with the heme type prosthetic group of cytochrome P450 as primary hepatic enzyme in oxidative drug biotransformation. Therefore, they can catalyze these oxidations. Concerning economical aspects and the poor stability of metalloporphyrin, their immobilization onto or into solid carriers can be promising solution. This study presents a novel immobilized metalloporphyrin nanocomposite system and its potential use as biomimetic catalysts. The developed two-step immobilization procedure consists of two main steps. First, the ionic binding of meso-tetra (parasulphonatophenyl) iron porphyrin onto functionalized magnetic nanoparticles is established, followed by embedding the nanoparticles into polylactic acid nanofibers by electrospinning technique. Due to the synergistic morphological and chemo-structural advantages of binding onto nanoparticles and embedding in polymeric matrices the biomimetic efficiency of metalloporphyrin can be remarkably enhanced, while substrate conversion value was tenfold larger than which could be achieved with classic human liver microsomal system.

Electrospraying technique was used to create thin, homogenous, continuous perovskite film from precursor solution from minimal raw material. In this work we used methylammonium lead iodide perovskite solutions to electrospray on an indium tin oxide substrate at different temperatures. After optimizing the spraying parameters, quasi-homogeneous thin film was formed. Moreover, thermal, and solvent annealing helped to increase the crystal size and reduce porosity.

AB - Built-in Thermal Test is a key method to assure reliable operation during the product life time. Pre-integrated architecture is a design concept for cyber-physical systems to reduce R&D efforts. In this work the built-in thermal test methodology was adapted to this design concept and its operation was demonstrated in a chemical flow-reaction system where the reactor’s thermal interface was qualified. The demonstrational measurements showed that the system was able to distinguish different reactor assemblies with intentionally degraded thermal interfaces with a resolution of 0.05 K/W.

AB - The Joint International Master in Smart Systems Integrated Solutions (SSIs) will graduate candidates for the ever-growing industry of Smart Systems, ubiquitous in all sectors of society including healthcare, transport, environment protection, energy and security. SSIs is given jointly by three universities in three European countries: Aalto University (Helsinki, Finland), University of South-Eastern Norway (USN), and Budapest University of Technology and Economics (BME) (Hungary), utilizing the complementary expertise and laboratory facilities of the three partners to create a unique programme with a more holistic approach than a single university could give. The programme collaborates closely with industry, and has EPoSS as Associated Partner, assuring its relevance. SSIs builds on the Joint International Master in Smart Systems Integration (SSI), which has been running since 2013 with Heriot-Watt University (Edinburgh, Scotland) co-ordinating a consortium with USN and BME.SSIs students benefit from the combined expertise of the consortium, as well as from the extended socio-cultural knowledge obtained by living in three different European countries that represent distinctively different aspects of the diverse Europe. The students in the programme show excellent performance, and the employability of graduates has proven to be very high. © 2021 IEEE.
